Comment on "Impact of frailty on clinical outcomes and resource utilization of hospitalizations for renal stone surgery".

This letter is a comment on a study titled "Impact of frailty on clinical outcomes and resource utilization of hospitalizations for renal stone surgery." The authors commend the study for its efforts to explore the relationship between frailty and surgical outcomes in urolithiasis management. However, they raise several concerns that require further clarification. They suggest that the frailty assessment used in the study may not capture all dimensions of frailty, such as psychological and social factors. They also recommend considering the gradation of frailty into non-frail/robust, prefrail, and frail states for a more nuanced assessment. The authors highlight the need for a more diverse dataset to validate the findings and suggest that the statistical analysis could benefit from a more detailed justification. They also express interest in exploring specific prehabilitation interventions and their practical application in urolithiasis management. Overall, while the study contributes to our understanding of frailty in renal stone surgery, addressing these areas could enhance the depth and applicability of the findings.
